1792 ECCW Narrow Linewidth CW External
Cavity Laser Diode
The 1792 ECCW series external cavity laser is a cost effective solution
for a coherent laser source. The laser is fabricated in a 14-pin
hermetically sealed butterfly package that incorporates a bias tee
circuit, an integrated thermoelectric cooler (TEC), a thermistor, and a
back facet monitor photodiode. The 1792 ECCW provides substantially
lower phase noise and a longer coherence length than other
semiconductor lasers, including DFB lasers. The wavelength stability is
assured by design, eliminating the need for wavelength lockers and
complex feedback control circuits.
